What is a storage cell?What does it store and how?Solution in Bengali

A heating element using nichrome connected to a 230 V supply draws an initial current of 3.2A which settles after a few seconds to a steady value of 2.8A. What is the stready temperature of the heating element if the room temperature is ${27}^{\circ }C$? Temperature coefficient of resistance of nichrome averages over the temperature range involved is $1.70\times {10}^{-4^{\circ }}{C}^{-1}$.
